I'm using Firefox for years, after Chrome started to ask me for a login (at around version 40). Never looked back. One day I woke up to a chart showing browser market share of FF at around 4%, which surprised me - as I thought many people would understand the implications and directions.
Maybe I'm too optimistic.
Update: Loved chrome, used it for years, I also love most Chrome engineering and all the innovation they added to the field - it's just good to have alternatives.
Its certainly low, but I also think FF usage is under reported due to built-in tracker blocking. For reference, FF uses the level 1 disconnect.me block list, which blocks StatCounter scrips from loading on 3rd party sites [1].
